The Southeast Savannas bioregion, located in the Northern America (Nearctic) realm, covers much of the Atlantic seaboard and the Southeast U.S. Savannas & Forests subrealm. It consists predominantly of coastal and conifer savannas but includes the Atlantic coastal pine barrens in the north and the Mississippi lowland forests to the west. The bioregion contains four ecoregions – Mississippi Lowland Forests (337), Atlantic Coastal Pine Barrens (347), Mid-Atlantic US Coastal Savannas (393), Southeast US Conifer Savannas (399) – and includes adjacent marine areas in the Atlantic Ocean and the Gulf of Mexico, as well as the lower section of the Mississippi River. The total land area of this bioregion is approximately 73 million hectares. 

The Southeast Savannas & Riparian Forests bioregion is part of the Southeast U.S. Savannas & Forests subrealm and is made up of four ecoregions: (1) Mississippi Lowland Forests (2) Southeast US Conifer Savannas (3) Mid-Atlantic US Coastal Savannas (4) Atlantic Coastal Pine Barrens.
